PRINTING-PRESS APPLIANCE.

To all whom it mag concern:

Be it known that l, Janus DOYLE, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Printing-PressAppliances, of which the following is a specification, the principle of the invention being herein eX- plained and the best mode in which I have contemplated armlyinp: that principle, so as to distinguish it from other inventions.

My invention is associated with. a printing press. while its more specific nature is an llll])l()\'t}lll9lll'. with an appliance calculated to perfect the finished impression.

The object is the provision of; means which will positively and continuously remove even minute sediment from the sheet just prior to its contact with the ink and so insure solidly inked areas and half tones which will be uniformly unspeckled.

The. said invention consists of means hereina'lter fully described and particularly'set forth in the claims.

The annexed drawingaiul the following description set. forth in detail certain means embodying my invention,- the disclosed meunsj however. constituting but one of various mechanical forms in which the principle of the invention may be applied.

l ig'ure 1 is a plan of a-two-revolution cylinder-press, a portion of the cyliiuler be ing cut away to better disclose the application of my inventive appliance. Fig. 9. is an end elevation ot' Fig. 1. Fig. 3 is a vertical section .on line llllll ot' Fi f. 1 looking in tlicdirlartioi'i oi. the arrows. Fig. l an enlargual section of line IV JV of Fig. l, lilo-m i; '0 looking in the direction of the arrows.

"llic ccmstruclion shown, as sutlicicnt for the purpose in hand. comprises the frame A upon which are mounted preferably integral standards the rear and forward pairs licing respectively designated 1/ and a. :dounicd lit'liss the frame in suitable hearings 1), directly above the standards a, is a primary shaft l1 and rotatably mounted upon this shaft is an improved type of cylinder press proper 7/ about which the paper sheets to be printed are intended to be twice revolved.

' "lhc successive sheets are automatically coniricliel to travel with the periphery of the iiulcr through the n'icduuh of gripping thanissu which, since ll forms no part oi:

Patented NOV. 12,1912. Serial No. 684,111.

th s invention 18 designated entire as 6 r 1 .Fhedirection 0i movement of the paper whlch has been marked by the reference character P is contra-clockwise according to the direction of vision in Figs. and 3 after approaching from the right and continuing again horizontally to. the left. Mounted upon one extremity of the shaft B is adriving pinion b.

A. stub shaft C is mounted in suitable bearings-cv situated approximately over the standards 11 Fixed in turn near the outer end ofthe shaft C and in fact so as to inter-. sect the same vertical plane as the pinion; b is a gear which is adapted to mesh there with as clearly seen in Fig. 1. A coin c the operative purpose of which will be directly nimifested is keyed to the shaft C eX- teriorly adjacent the gear 0 I also mounted for movement across the stand ards a within suitable bearings d. A. pair of actuating levers (Z (Z are keyed intermediately of their lengths to opposite ends of the rod D. The lever (l is somewhat. longer than the lever (Z and rests within substantially the same vertical plane as the cam c Secured to the upper extremity of the lever Wis a roller (5* whose lower. extremity is yieldingly attached to th frame A through the agency of the tension spring (Z whereby the roller is normally held in engagement with the surface of the cam. As should now be apparent the movement of the cylinder 3') is transmitted in sequence to the pinion 7). gear 0 and cam and hence to both the-levers (l and (Z in the form of intermittent oscillatory movement toward and away from its own surface.

Fixedly mounted upon the two levers d (1 is a member E to which a plurality of brushes 0' are removably attached by means of screws The brushes 0' project toward and are adapted to intermittently contact with the surface of the cylinder 71. The periods of contact are necessarily determined by the oscillation of the levers dial and agreeably predeterinined by the peripheral contour of the cam in order to insure the operative results which are sought. Also mounted in bearings d upon the levers r1 (Z and likewise and necessarily extending across the frame, thougl'i, below the brushes c, is a pipe F. This pipe is provided with:

a longitudinal slot f and is capable of being fixed in various positions about its own axis A rod D is I .th oughthe medium 'of set screws f whereb the location of the slot with respect to bpth the cylinder 6' and brushes 6 may be altered at will. In the exemplification hown the central part of the ipe is pro-' v1ded w1th.a.T'f with whic of delivery of, successive sheets to have the cylinder revolve twice for each sheet that is to-be printed, and furthermore to have the brushes 6' held out of engagement with the surface of the cylinder until immediately after the front edge of the sheet with its attached and outwardly projecting gripping mechanism 1) has passed, and since no novelty is alleged as regardssuch'arrangement; the peripheral surface of the cam 0 will be presumed as of a contour to meet the above requirements. Any individual sheet on ap- I I will be with that part of the peripheral surface of the cam c which is immediately in as requiredfor consummate neatness.

proaching as already stated from the right,

will be gripped and drawn diagonally downward to the left as appears in Eig. 3.'

Just prior to the passage of its frontedge beyond and below the arc ofoscillation of the brushes e the contact of'the roller d advance of its depressed portionnas clearl indicated in Fig. 2. Consonantly, immedl ately after such front edge has passed the brushes, they will be permitted to contact the remaining area of the sheet and so perform their function; In the meantime all particles of sediment will be continuouslyremoved by enforced passage through the pipe F and the sheet presented to the ink Having thus described my invention what I claim is:

1. A printing press appliance comprising the combination of sheet conveying means, a slotted duct movably mounted across said conveying means, means for reciprocating said duct toward and away from said c0n-. veying means, means for adjusting the disposition of. said slot with respect to said conveying means, and suction means opera: v

- tively connected with saidductl.

2. A printing press appliance comprising the combination of sheet conveying means, a movable supporting member, a' brush mounted thereon, a ductadjustably mounted upon said member and provided with a duct being positioned beyond said brush,

and means for establishing a suction Within 'Said duct. a

. 4. A printing press appliance comprising the combination of a' sheet conveyer, a pair of levers positioned laterally thereof, a brush mounted upon said levers and adapted to contact with said sheet, a suction duct having a slot and adjustably' mounted upon said levers, means for eifecting'jh'e movement of said levers" relative to said conveyer, means for fixing said duct, and' suction means communicating with the latter. v

1 5. A printing press appliance comprisin the combination of a frame, a cylindricfi sheet conveyer mounted for movement thereon, a lever upon said frame, means for moving said lever, a brush removably secured to the latter and adapted .to engage said sheet, a duct rotatably mounted upon said lever and having a slot extending across said conve er, said duct being positioned beyond sai brush, with-reference to the direction of movement of said conveyor, means for fixing said duct in various positions about its axis, and means for establishing a suction withinsaid duct.
